.HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 237,684, dated February15, 1881. Application filed June 1, 1880. (No model.)

To all whom it may concern:

Be it known that I, OHns'rnR B. Hosnonn, of the town of Williamsburg, inthe county of Hampshire and State of Massachusetts, have invented newand useful Improvements in Hose-Nozzles, of which the following is aspecification,reference being had to the accompanyin g drawings, whichform part of the same.

My invention relates to that class of hosenozzles which are designed tothrow either a solid stream or spray; and it consists in apeculiarconstruction of the body and plug, so that when the latter is turned inone direction 1 a solid stream of water is thrown from the nozzle, andwhen turned completely around a spray of water is thrown from the samenozzle or mouth-piece and, further, in the construction whereby an equaldistribution of water to form the spray is obtained, and also toincreasing its velocity, and which construction is fully shown in theaccompanying drawings, described in the specification, and referred toin the appended claims.

In the drawings, Figure 1 is a sectional elevation, on the line a; an,of a hose-nozzle embodying my invention. Fig. 2 is a side elevation ofthe body of the same. Fig. 3 is a cross-section of same on the line 3 y.

A is the body of the hose-nozzle, and is supplied with severalpassage-ways, which will be fully described hereinafter. The end of thebody next to the hose is provided with a female screw, B, into which theend of the hose is screwed. The body A is furnished with a transverseconical hole or seat, 0, into which the plug G fits and works. Openinginto this hole, from the end next to the hose, are two passages, E andF. The body on the other side of the hole 0 is provided with a malescrew-thread and an annular recess or depression, H, the object of whichis to equalize the distribution of water to form the spray, and also toincrease the velocity through the agency of the small oblique holes h,which will be hereinafterset forth. Opening into this annular recess H,and also into the hole 0, is a passage, F and there is also a passage,E, which extends from the hole Othrough to the end of 50 the bodyfarthest from the hose. This is shown in Figs. 1 and 3. Fitting andworking in the hole or seat Gis a hollow plug, G, which is provided withtwo holes, 9 g, from interior to exterior, one on either side. When theplug is in the position shown in Fig. l the hole 9 is exactly in frontof passage F, and the hole g is in front of passage F but when the' plugis turned one-half a revolution the hole 9 is in front of passage E, andhole 9 is in front-of passage E. Opening. from the annu- 6o lar recess Hare several small holes, h, drilled or cast in an oblique position withrelation to the direction of the line of the hose-nozzle, as shown inFig. 2. By having a series of small holes, through which the water isforced from the annular space H, the velocity of the water is increased,and also the flow is equally distributed, and which equalization nevertook plaoein hose-nozzles as previously constructed. The object ofhaving these holes oblique is, that they cause the water to rotate andemerge from the nozzle end in the form of spray.

Screwed over the outer end of the body A is the nozzle end I. When thisend I has been screwed up against the leather packing-ring 7 5 J thejoint is perfectly tight, and the annular recess now becomes an annularpassage, Fig.

1, for the purpose of equalizing the distribution of the water to formthe spray.

The operation is as follows: To throwastream in the form of spray theplug Gr is turned as shown in Fig. 1. The water from the hose passesthrough passage F, hole 9, through hollow plug Gr, through hole 9 andpassage F, into the annular space or passage H, from which it passesthrough the small oblique holes h it into nozzle end I. In passing fromthe annular space or passage H through holes h an equalized distributionand a rotary motion is imparted to the water, and retained by it 0 whenit emerges from the mouth of the nozzle end, where centrifugal forceacts upon it, and the water is thrown in alldirectionsin the form ofspray. 'To throw a solid stream of water the plug is turned one-halfarevolution. The water then passes through passage E, hole g, throughthe plug G, through hole g, passage E, into the nozzle end, and finallyleaves the nozzle in a straight and solid stream without rotary motion.10o

I am aware that nozzles have been designed for this purpose before, butnone have had the peculiar construction embodied in my nozzle,consisting in the construction of an annular passage, in combinationwith oblique holes, for the purpose of rotating the water and causing anequalized distribution from the same, and also an increased velocity.

I do not consider that it would alter my invention if, instead of holesE, I and g, theholes E and F were made in one, and the plug G suppliedwith a corresponding hole of greater width, and another holecorresponding to hole 9 on the level of passage E, but not on the samevertical line with the hole g, for the annular space and equalizeddistribution and increase in the velocity of the water is the essentialfeature of my invention.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a hose-nozzle, the combination of body A, provided with passages Fand E, annular passage H, and oblique holes h, for equalizing thedistribution of water to form spray, and increasing the velocity, with ahollow plug, G,

provided with holes 9 g and nozzle end I, substantially as and for thepurpose specified.

2. A hose-nozzle formed with an annular chamber, H, and with smalloblique holes h, for equalizing the distribution of the water to formspray, and increasing its velocity of discharge in a rotary motion,substantially as and for the purpose specified.

3. In a hose-nozzle, the hollow plug G, provided with holes g g onopposite sides of the plug and on different levels, in combination withthe body A, provided with acentral passage, E, and a side passage, F,the central passage leading directly into the nozzle end, and the sidepassage leading into an annular distributing-chamber connecting with thenozzle end by means of oblique holes, substantially as and for thepurpose specified.

4. In a hose-nozzle, the body A, provided with annulardistributing-recess H, oblique holes 72, and nozzle end I, substantiallyas described.
